Benefits of technology
This approach minimizes waste and reduces processing time by maintaining a consistent temperature while dynamically adjusting the cutting speed to match local conditions, ensuring accurate and efficient cuts.
Problems solved by technology
After this introduction, a remarkable technical inconvenience occurs in the prior art, which frequently affects the quality of the end product negatively, even with the risk of product waste.
If it does not take place, a progressive bending of the wire may cause an inaccurate cut, as the feed advancement is too fast in respect to the melting speed of the material.
On the contrary, a too warm wire with a too slow feed advancement causes an excessive local melting of polystyrene with an irregular cut, leading to product waste.
In that sense, it is not possible to standardize overall speed and temperature values for all types of pieces, as each piece can have a hardness and / or impurities that requires modifications of such parameters.
Obviously, as mentioned, such process is very rudimentary and leads to approximate results.
Moreover, the inaccuracy of the set parameters arises during cutting, thus leading inevitably to a qualitative waste of the product and compelling the operator to select another block, hoping that, as a consequence, parameters will be better set than before.
The foregoing deficiencies in prior art processes cause a high amount of waste and a huge waste of working time.

Embodiment Construction
[0061]With reference to FIG. 1, a wire 2 is represented schematically for cutting polystyrene and it is linked at its ends to two sliders 1. The figure represents schematically a block 100 which, as example, is cut by the wire 2 in such a manner so as to obtain a series of elongated pieces with square section (3, 4, 5).
[0062]Therefore, the wire follows a cutting path represented by the dashed line and which comprises a vertical section, a second horizontal section and then the production of elongated pieces placed side by side with a sequence of horizontal and vertical motions.
[0063]Obviously, this cutting pattern is only an example of many possible cutting patterns, as, depending on geometries, the motion of the wire 2 can also have different directions, such as diagonal and / or curved.
[0064]As shown schematically in FIG. 2, the advancement motion speed may be too high during the cut, due to the kind of block to be cut, thus leading to wire bending. In fact, FIG. 2 shows schematical...

An assembly for cutting a polystyrene block includes a lever element, adapted to be coupled to a hot cutting element, and a control device connected thereto. The lever is arranged so that a potential inclination of the hot cutting element can be followed during the feed motion of the cut, the lever further cooperating with a sensor set to detect a potential inclination deviation of the lever during the cut, in relation to an initial reference inclination, the control device being set to vary feed motion speed depending on the detected variation of inclination.
Description
TECHNICAL FIELD[0001]The present invention refers to the technical field of equipment for cutting polystyrene.[0002]In particular, the invention refers to equipment configured to make cuts, according to preset geometries, that prove to be particularly precise, thus minimizing errors and waste.BACKGROUND ART[0003]Machineries for cutting polystyrene blocks to obtain specific forms have been known for a long time.[0004]Polystyrene cutting, starting generally from initial blocks, allows obtaining products with various geometries, used in many fields, for example interior design, art and buildings.[0005]Polystyrene cutting is generally made by a metal wire, which is heated to predetermined temperature through the passage of electric current, thus taking advantage of a resistive effect, named Joule effect.[0006]Each wire is linked at its ends to two sliders that are mobile towards one or more directions, for example along a horizontal and vertical axis or following curved or diagonal path...
